Accessing a Kafka Premium Instance

Public Access
-
To access a Kafka instance over a public network, you can enable public access and configure public network bandwidth for the instance. After the instance has been created with public access enabled, you can modify the public network bandwidth. Currently, you can increase but cannot decrease the bandwidth.
In some regions, public access cannot be enabled for Kafka instances whose bandwidth is set to 100 MB/s.
